The Rota-sludge method is an adaptation of the Indian hand sludge method. The hardened drill bit is turned 90 degrees during drilling thus chiselling the bottom of the hole. This technology can be used to drill 2-5 inch wells in layers with sand, clay, gravel, tuff stone or weathered rock.
History and social context
Suitable conditions
Can drill 2-5 inch wells to 20 meter.
